LOOM SHUTTLE.

Application filed. April 5, 1921. Serial No. 458,645.

T 0 all whom it may concern.

Be it known that we, Janus IVILLIA Boo'rri and THOMAS CRAVEN CORLASS, subjects of the King of Great Britain, and residents, respectively, of Mountlloyd, Highfield Lane, and Sunny Mount, both in Keighley, in the county of York, England. have invented a certain new and useful Inr provement in Loom Shuttles, of which the following description, having reference to the accompanying sheets of drawings, is a specification.

In loom shuttles it is most usual that the bobbins or cops of weft are mounted therein so that the thread may be withdrawn from the shuttle through the shuttles eye atone end thereof thus when the shuttle travels with that end of it in which the eye is situated at the leading end, the weft is carried into the shuttle box for a distance extending from said eye of theshuttle to the entrance of said shuttle box, thus permitting said weft to become entangled or to be cut by the shuttle pressing it against the edge of theshuttle box as well as exposing said weft to other detrimental actions. In order to obviate this we produce a shuttle according to our invention which will carry the weft into the shuttle box under such conditions that it is equally free from the disadvantages referred to at one side of the loom as it is at the other side where the eye of the shuttle is at the rear and not at the leading end of same. Our said invention consists in forming a groove longitudinally along the outer side of the shuttles wall to be of such formation that the weft on passing through the eye of the shuttle when said shuttle is traveL ling in the direction where said eye is at the leading end of said shuttle so that said weft will be received by the groove the outer wall of which protects it equally well as the weft is protected when the shuttle travels in the opposite direction and with the weft only extending from the eye to the outer end of the shuttle.

Fig. 1 is a side elevation of a shuttle showing the application of our improved parts.

Fig. 2 is a sectional plan of the shuttle shown by Fig. 1.

Fig. 3 is a sectional end elevation drawn to an enlarged scale of the shuttle shown by Figs. 1 and 2.

Fig. 4 is a perspective view of one end of the shuttle so as to illustrate the formation of a certain part hereinafter described.

Fig. 5 is a perspective view showing the construction of a part in detail hereinafter explained.

Figs. 6 and 7 are similar views to Figs. 1 and 3 respectively but illustrate modifications hereinafter described.

In carrying our invention into effect we form the side wall a of the shuttle 2 so that av groove or furrow 10 (according to one arrangement) will be formed by fixing a metal plate 3 upon this outer surface of said wall. Preferably we form this plate 3 to' be detachable and further when it is detached from its position upon the wall of the shuttle a it will be of a curved character shown by Fig. 5 so that when fixed in position thereon its inner surface is made to press against the wall a of the shuttle 2 so that the position it assumes brings it straight and even with the outer surface of the other part of the shuttles wall as is shown by Figs. 2 and 3.

This metal plate 3 is further of such formation that when mounted in position its upper edge I) is of a peculiar curved character its curvature commencing at a point cl nearer the outer or tip end of the shuttle 2 than is the eye 4i for the weft, thus as the weft comes out of or through said eye at the travelling of the shuttle 2 with said eye in the leading direction as indicated by the arrow 0?, the pull of the shuttle upon said weft causes this latter to slide up and over the curved edge 6 of the plate 3 and then to descend into the groove to from which it extends in alignment with the wall (4, thus in this position it is fully protected against any possibility of being caught or pressed between the outer surface of the shuttle and the front wall of the shuttle box.

The metal plate 3 is preferably made detachable so that its adjustment in position and any damages connected therewith may be more readily attended to by the attendant being able to remove said plate 3 as may be found desirable.

This plate 3 may be fixed by screws or otherwise but preferably we form said plate 3 so that its outer ends 9, g are bent upon themselves to form cylindrical parts as shown by Fig. 5. These cylindrical parts g, g of the plate 3 are made to take into openings made in the body of the shuttle 2 wherein are also placed buffer pieces 5 which may be of india rubber, leather or other appropriate buffer material, thus the plates 3 are firmly held in position and during the operations of the shuttle and the checking of same when arriving the shuttle box enables the buffer devices 5 to withstand the concussion and shocks of the plates 3 as will be understood. 7

The wall a of the shuttle has also formed in it a slot or groove 10 which is made for the-space shown in broken lines by Fig. 1 and as shown by Fig. 2 to extend for an appropriate space into the interior of the shuttle. By this formation of the slot 10 as the shuttle is travelling in the direction indicated by the arrow at the weft on emerging through the eye it of said shuttle is constrained (as and for the purpose already stated) to move over the curved edge I) of the plate 3 and then to fall into the slot w when the shuttle is travelling in the direction indicated by the arrow When the shuttle 2 is thrown or projected in the opposite direction to that indicated by the arrow 00 then the weft lying in the groove w is permitted by its tension being reduced to fall through the slot 10 into the space within the body of the shuttle 2 thus its entanglement which otherwise would occur (provided it was not thus allowed freedom to turn or bend upon itself) is entirely avoided, while yet the actions of the other protecting parts described are not interfered with.

We have hereinbefore described the con struction of the shuttle 2 with a detachable plate 3 but we would have it understood that we are aware that it may be possible to form the grooves 10 and '10 in the wall a of the shuttle 2 by cutting same therein so that the outer part of said wall a is formed integrally with the inner part thereof as is illustrated by Figs. 6 and 7 of the drawings. In this case also we take care that the upperedge b of the part of the wall a is still of the curved formation hereinbefore described and we form it to commence ap proximately level with the centre of the eye 4: in order to ensure the perfect guiding of the weft as it emerges from said eye l.

Such being the nature and object of our said invention, what we claim is 1. A loom shuttle comprising a body part having a slot formed longitudinally in its front wall, a guide eye formed through the front wall of said body part, said front wall of the body part having a longitudinal groove formed therein and the outer part of said front wall having its upper edge curved and extending from near the eye of the shuttle where it is approximately in alignment with the centre of the guide eye, to a similar distance from the other end of the shuttle.

2. A loom shuttle comprising a body part with a guide eye or opening for the weft formed through said wall at a point near one end of said body part and a double outer wall forming the front part of said shuttle, the front portion of said double wall commencing with a curved part which extends crosswise the centre of the guide eye and has its upper edge of the curved character described so that it terminates in said front wall near the opposite end of the shuttle.

3. A loom shuttle comprising a body parthaving a guide opening made through the front wall thereof, a metal plate mounted upon the front wall and spaced from the outer surface of said wall to form a groove between it and said wall, said plate having its leading and terminating ends and its upper edge curved as described.

4 A loom shuttle, comprising abody part having a guide eye therethrough, a metal plate mounted on the body to form a groove between it and the front wall of the body, said plate being shaped so that its outer ends enter into openings in the body of the shuttle, and means for resiliently retaining said plate in its position upon the body part.

5. A loom shuttle comprising a body part having an opening or guide eye for the weft made through the front wall thereof another opening lV being formed through the said front wall and a plate mounted upon said body over the opening lV and forming a longitudinally extending groove between it and the front outer surface of the body part, said plate having its upper edge curved.
